The spectral composition of the Sun’s output is not constant but varies over multiple timescales, from days to decadal cycles. Solar spectral irradiance variability (SSI) refers to the changes in the ...

In a new weekly update for pv magazine, Solcast, a DNV company, reports that this winter brought dry and warm conditions to most of South America, resulting in higher-than-normal irradiance across the ...

In a new weekly update for pv magazine, Solcast, a DNV company, reports that solar irradiance surged far above the March norm in the US South and Midwest, while parts of the US West and Canada were ...

An approach to improve the performance of floating photovoltaic (FPV) systems by incorporating the complex interplay among ...

Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation as measured in the wavelength range of the measuring instrument. The solar irradiance is ...

Without quality control, even expensive, high-precision radiometers can generate misleading data, according to Solargis' ...

Fluctuations in solar radiation are a problem for solar power plants as they cause problems in the power grid and other reliability issues. In a recent study, scientists aimed to deepen our ...

The study of Photosynthetically Active Radiation (PAR) and solar irradiance lies at the intersection of plant science, meteorology and renewable energy research. This field investigates the solar ...

A very small instrument has a big job ahead of it: measuring all Earth-directed energy coming from the Sun and helping scientists understand how that energy influences our planet’s severe weather, ...

Review of NOAA Working Group Report on Maintaining the Continuation of Long-Term Satellite Total Irradiance Observations evaluates NOAA's plan for mitigating the loss of total solar irradiance ...
